The crazy strand model found here is the best April fool in a long time: a model that claims to be the theory of everything - with simple math.
All the famous string theorists with their incomprehensible concepts and their useless abstractions are left behind by an unknown guy who claims to have found the secret behind the three dimensions of space, the three gauge interactions and the three generations. The model claims that you can describe quantum theory and general relativity with strands, using math that every 20-year old can understand.
It might be an April fool, but is such a good one that it is worth telling.
